How to pixelate or censor part of an image

Pixelation hides sensitive detail with a mosaic effect. Here's how — and when to use a solid box instead.

Open Pixelate Image

Steps

  • Open the pixelate tool and drop your image.
  • Increase the block size until the detail is unreadable.
  • Export the pixelated image.

Pixelation vs true redaction

A large block size makes text and faces unreadable for everyday sharing. But for genuinely sensitive data, draw a solid box over it instead — heavy pixelation can sometimes be partially reversed.
